The vehicle plays the music in the new video from OK Go in conjunction with Chevrolet. This took four months of preparation and four days of shooting. From their website:

So let’s not forget the true meaning of Sunday — OK Go in a super-hacked Chevy Sonic, playing 288 guitars, 55 pianos, and 1,157 homemade instruments while Damian acts as a stunt driver. (He took lessons.) It’s truly the little things that are meaningful.

I remember being cynical, too. It goes away and eventually you learn to enjoy silly things like this again. If not, you end up growing a 70s mustache and wearing skinny pants and only taking picture on plastic kids' cameras you find in Goodwill.

Why does the Youtube video run a Scientology ad? OKGo aren't another example of the "cool-seeming people who turn out to be retarded" phenomenon, are they? (And yes, I know that a few seconds' worth of research on my own part would clear this up; it's like looking at an eclipse: you want to limit the exposure)
